block: Fix bdrv_has_zero_init

Assuming that any image on a block device is not properly zero-initialized is
actually wrong: Only raw images have this problem. Any other image format
shouldn't care about it, they initialize everything properly themselves....

block: Replace u_int8_t, u_int16_t, u_int32_t, u_int64_t by standard int types

There is no need to have a second set of integral types.
Replace them by the standard types from stdint.h.

Make default invocation of block drivers safer (v3)

CVE-2008-2004 described a vulnerability in QEMU whereas a malicious user could
trick the block probing code into accessing arbitrary files in a guest. To
mitigate this, we added an explicit format parameter to -drive which disabling...

block: add sheepdog driver for distributed storage support

Sheepdog is a distributed storage system for QEMU. It provides highly
available block level storage volumes to VMs like Amazon EBS. This
patch adds a qemu block driver for Sheepdog.

Sheepdog features are:...

qcow2/vdi: Change check to distinguish error cases

This distinguishes between harmless leaks and real corruption. Hopefully users
better understand what qemu-img check wants to tell them.

raw-posix: Fix test for host CD-ROM

raw_pread_aligned() retries up to two times if the block device backs
a virtual CD-ROM (a drive with media=cdrom and if=ide, scsi, xen or
none). This makes no sense. Whether retrying reads can correct read
errors can only depend on what we're reading, not on how the result...

blkdebug: Fix set_state_opts definition

The list head was initialized to point to the wrong list, so all actions ended
up being handled as inject-error even if they were set-state in fact.

blkdebug: Free QemuOpts after having read the config

Forgetting to free them means that the next instance inherits all rules and
gets its own rules only additionally.

blkdebug: Initialize state as 1

state = 0 in rules means that the rule is valid for any state. Therefore it's
impossible to have a rule that works only in the initial state. This changes
the initial state from 0 to 1 to make this possible.
